This pamphlet discusses the benefits of using the Schoolwide Enrichment Model (SEM) for providing numerous enrichment and acceleration alternatives that are designed to accommodate the academic strengths, interests, and learning styles of all middle school students, including gifted students. It explains the different components of SEM including the Total Talent Portfolio, a vehicle for systematically gathering, recording, and using information about students' abilities, interests, and learning style preferences. Curriculum modification techniques that are used in the SEM are then described and include adjusting the pace and level of required material to accommodate variations in learning and providing enrichment and acceleration alternatives for students who have, or can, easily master regular material faster than the normal pace. The use of enrichment clusters for non-graded groups of students who share common interests and come together to pursue these interests during specially designated time blocks is also explained, along with types of enrichment clusters and cluster goals.
